Title: Cup-shaped rotor for electromagnetic appts. - comprises a sintered composite mfd. by powder metallurgy
Inventor: GROSSE JOACHIM DIPL PHYS
IPC: H01F1/20
Filed: 1978-06-02
Abstract: Structural components, which are stressed electromagnetically and thermally and of which the side walls are 4 time the wall thickness, are produced by powder metallurgy, the side walls being composed of several phases side-by-side, and evenly distributed along the wall. One phase at least is ferromagnetic and at least one other has a good electrical conductivity. Component is produced by filling a mould with the powder mixt. composed of the two materials so that the layers extend parallel to the longitudinal direction, compacting and sintering under a protective gas atm. or vacuum without the formation of a liq. phase, and extruding the sintered body, which is free of cracks or blowholes and of 95% density, to the final shape with a material flow in the longitudinal direction. Method produces structural components of superior conductivity and electrical properties, and is partic. suitable for the prodn. of motor rotors.
Patent DE-2827913-A1 (DE)
Title: Work rotation speed control for forging machine - uses tachogenerator to supply current to brake and smooth rotation of work cage
Inventor: GOELITZER ERNST
IPC: H02P29/00
Filed: 1978-06-26
Abstract: a rotary forging machine for forging the barrels of firearms has a rotating cage with radially sliding hammers with attached tools. As each hammer passes one of a large number of rollers, which run in an outer track, it receives a radial impact which is transmitted to the workpiece. The workpiece tends to rotate with the cage but an irregular speed. To control this speed a tacho-generator is fitted to an extension of the mandrel, which generates a current proportional to the speed of rotation. This current is used to control a brake which in turn controls the speed.

Title: Eccentric cycloidal reduction drive - has elastic bushes on one set of drive rollers to reduce backwash
Inventor: HABERDITZL ANTON
IPC: F16H25/04
Filed: 1978-08-17
Abstract: A drive consists of an input shaft (1) and an output shaft (6), separated by two eccentrically-mounted cycloidal cam plates (13, 14), rotating within a concentric ring of outer rollers (15) mounted on the drive housing (4).

Title: Inductive two-wire proximity switch - uses oscillator switched ON and OFF by transistor connected to induction coil
Inventor: GEHL WILLFRIED DIPL ING
IPC: H03K3/014
Filed: 1979-04-12
Abstract: The inductive two-wire proximity switch includes an oscillator which generates HF AC when no object is near the switch but which is damped when a conductive object is brought near the switch and enters the HF field produced by the oscillator. The damping of the oscillator causes it to cease oscillating and when in its non-oscillating mode the oscillator draws less current than when oscillating. The circuit includes a transistor (6) acting as a controllable switch. Its collector is connected to the oscillator circuit (1) and its emitter is connected via a resistor (7) to the positive terminal of the circuit. The base of the transistor (6) is connected via an auxiliary coil (3) to a diode (4). This coil (3) is inductively coupled to the coil (2) in the oscillator circuit. The diode (4) is directly connected to the positive terminal of the circuit, and also via a capacitor (5) to the base of the transistor (6).

The support profile and the table come into contact with each other, before the edge of the cutting blade reaches the table.
Patent DE-2940236-A1 (DE)
Inventor: ISLER ERWIN
IPC: E01C13/04
Filed: 1979-10-04
Abstract: The floor-covering panel (10) comprises webs (12, 13) which are located perpendicularly with respect to one another and by means of which the walking surface is formed. The webs are formed by upended bars, the narrowest sides (16), forming the walking surface, of which are chamfered in the form of a roof ridge. At the points of intersection, the bars are widened on the underside and form cross-like supporting feet. Moreover, the panel has expansion joints (10a, 10b) which run parallel to the webs and have coupling elements (19) which are designed in a Z-shape and, due to their mutual, clamp-like arrangement, provide a connection which is pliable under impact and rigid under tension. The edge parts are provided with hook elements (18) and receiving elements (17) in order to be able to form a continuous floor covering. The roof-ridge-like design of the upended bars results in low oxidation and thus in a relatively low crack formation with high stability of the webs, which cannot form slippery surfaces even when subjected to a large amount of use. The connecting lugs (18a) of the hook elements (18) define a joint between adjoining panels to absorb changes in length caused by heat, and, in addition, they form, together with the expansion joints (10a, 10b), an elasticity of the floor covering which takes effect in the horizontal direction. <IMAGE>
